Zuckerberg: I'm 'quite sure' I own Facebook

Mark Zuckerberg last night addressed the question of whether he owes 84 per cent of Facebook to a New York firewood salesman.

His comments in a TV interview followed a federal court hearing on Tuesday, in which a Facebook lawyer said she was "unsure" whether Zuckerberg had signed a contract in 2003, which Paul Ceglia claims entitles him to a large share of the world's dominant social network.

"If we said that we were unsure I think that was likely taken out of context, because I think we are quite sure that we did not sign a contract that says that they have any right to ownership over Facebook," Zuckerberg told ABC News.

Of course, when he says "we", he really means "I". The dispute stems from when a student Zuckerberg was independently touting his services as a coder for hire.

Note that the 26-year-old CEO isn't saying he didn't sign any contract with Ceglia - in fact his lawyers have confirmed he did - rather he's "quite sure" that what he did sign doesn't grant equity in Facebook. Ceglia's lawyers say different, and that he invested $1,000 in what became Facebook, after employing Zuckerberg to work on a separate project. ®
